Answer:
1) cortical epithelial cells; (2) macrophages and dendritic cells
Explanation:
T cells, also known as T lymphocytes, are a fundamental type of cell of the immune system that determines the specificity of the immune response to specific foreign particles (antigens). T cells are produced in the Thymus (it is for that reason that they are called T cells) and then circulate throughout the bloodstream in order to recognize specific antigens in association with major histocompatibility complex (MHC) molecules on the surface of antigen-presenting cells (APC), such as macrophages and dendritic cells. T cells undergo positive and negative selection: 1- positive T-cell selection refers to the process by which T cells bind cortical epithelial cells that express Class I or Class II MHC molecules with enough affinity to get a survival signal; whereas negative selection occurs when T cells bind to macrophages and dendritic cells that express MHC specific receptors with a strong enough affinity to get an apoptosis (programmed cell death) signal.

Answer:
Find funding sources.
Explanation:
Once an action plan is developed, it is ideal to find sources of funding that will support the action plan to be carried out efficiently. These sources of financing promote economic resources, which are essential for the action plan to be implemented and for its objectives to be fully achieved.

"Healthy environment supports healthy and happy life." Justify it
Answer:
I think a healthy atmosphere promotes a happy existence. What makes us joyful varies from individual to another. Whatever we are exposed to, we usually discover what makes us happy. Most people tend to desire what they lack. We all make decisions that are difficult to reverse if we don't like the consequence. Then there are events beyond our control, both good and bad. I believe that when something uncontrollable happens to a person, they can feel discouraged and either give up on achieving happiness or take a long time to find the energy to start again.

might be prevented by not sharing a water bottle?
Answer:
B. Cold Sores because sharing the same water bottle can lead to catching diseases or othersicknesses that can be transmitted via saliva.
One disease that can be prevented by not sharing a water bottle is mononucleosis, also known as the "kissing disease" or "mono."
Sharing utensils, drinks, or water bottles with a person who is infected with mono, which is a viral infection caused by the Epstein-Barr virus (EBV), is one way to transfer the infection. Mono can also be shared by saliva. People can lessen their chances of becoming infected with the virus as well as reducing the likelihood that it will be transferred to others by not sharing water bottles.
It is essential to keep in mind that in addition to the virus that causes the common cold, other diseases and infections, such as some types of bacteria, can also be passed on from person to person through the sharing of water bottles. Therefore, maintaining proper cleanliness and avoiding sharing personal goods like water bottles are also important steps that may be taken to reduce the risk of contracting a variety of diseases.

what is mass
what is length
what is time
Answer:
mass is both of a physical body and a measure of it resistance to acceleration when a net force is applied.
the distance between any two points or place is called length.
the gap between any two events is known as time.
Answer:
Mass is a measure of the amount of matter in an object. Mass is usually measured in grams (g) or kilograms (kg). Mass measures the quantity of matter regardless of both its location in the universe and the gravitational force applied to it. An object's mass is constant in all circumstances; contrast this with its weight, a force that depends on gravity.
Length is the term used for identifying the size of an object or distance from one point to another. Also, length is a measure of how long an object is. The length of an object is its extended dimension, that is, its longest side.
Time can be defined as the ongoing and continuous sequence of events that occur in succession, from the past through the present to the future. Time is a used to quantify, measure or compare the duration of events or the intervals between them, and even, sequence events.
Explique tres consecuencias que se dan en una cadena alimentaria cuando desaparece alguno de los organismos
Answer:
- Desequilibrio de la red trófica
- Sobrepoblación de organismos del nivel trófico inferior
- Reducción de la biodiversidad
Explanation:
La cadena alimentaria (también conocida como cadena trófica) refiere a las relaciones alimentarias existentes entre los organismos que conforman una comunidad dentro del ecosistema. Estos organismos obtienen materia y energía a partir de organismos ubicados en el nivel trófico inmediatamente inferior. En la cadena alimentaria, los productores primarios son organismos autótrofos (por ej., plantas) los cuales elaboran sus propios compuestos orgánicos que a su vez son consumidos por los consumidores primarios (herbívoros). Subsecuentemente, los consumidores primarios sirven de alimento de consumidores secundarios (carnívoros menores), y así sucesivamente a lo largo de la cadena (consumidores terciarios, cuaternarios, etc). Los descomponedores son organismos dentro de la cadena los cuales se alimentan de restos orgánicos de organismos muertos o en descomposición, transformándolos en compuestos inorgánicos que ingresan nuevamente al ecosistema. La desaparición de los organismos de un nivel trófico generalmente supone un desequilibrio de la red trófica. Por ejemplo, la eliminación de los consumidores secundarios (carnívoros menores) supone un aumento de las poblaciones o sobrepoblación de consumidores primarios (organismos herbívoros) que se encuentran ubicados en el nivel trófico inmediatamente inferior, lo cual puede desencadenar una drástica reducción de las especies productoras (plantas) presentes en el ecosistema. Este fenómeno disminuye no sólo la diversidad de las especies productoras del ecosistema, sino que también altera las poblaciones que dependen directamente de los productores (por ejemplo, la población de polinizadores) en la comunidad.

Answer:
b. It is a consistent way of measuring the amount of alcohol in a drink
Th purpose of a standard drink measurement is to provide a consistent way of measuring the amount of alcohol in a drink.
When something is said to be a standard drink, it means that it has a certain amount of alcohol in it which in the United States is 14 grams of pure alcohol.
This allows people to be able to measure and compare drinks based on whether they are standard or not because a standard beer will be said to have the same amount of alcohol as a standard wine or a standard spirit.
People can then use this to determine how much of a certain drink they will take because they will know how the amount of alcohol in the drink regardless of what drink it is.

B. Cardiac arrest is an electrical disturbance and abrupt loss of heart function.
C. A heart attack can trigger an electrical disturbance in the heart.

The following descriptions of a cardiac arrest are all accurate, with the exception of An electrical disruption in the heart can be brought on by a heart attack. So, the correct option is C.
What is Cardiac arrest?The sudden, unexpected cessation of heart function, respiration, and awareness is known as a cardiac arrest. When this happens, the heart stops beating suddenly. If nothing is done about it right away, the person can pass away. Loss of consciousness and lack of response are the main symptoms.
The use of a pacemaker or urgent CPR is required in this medical emergency. Drugs, an implanted device, or other procedures may be part of hospital care.
The electrical system of a damaged heart malfunctions most frequently during cardiac arrests. An aberrant heart rhythm like ventricular tachycardia or irregular heartbeat is brought on by this defect. Another contributing to some cardiac arrests is a severe weakening of the heart's rhythm.
Therefore, the correct option is C.
